按照 Lumen 文件，在 unit test 中建立 HTTP request 要呼叫 $this->call()，但沒辦法自訂 header 內容。

細看實作 Laravel\Lumen\Testing\Concerns\MakesHttpRequests::call()：

/**
 * Call the given URI and return the Response.
 *
 * @param  string  $method
 * @param  string  $uri
 * @param  array  $parameters
 * @param  array  $cookies
 * @param  array  $files
 * @param  array  $server
 * @param  string  $content
 * @return \Illuminate\Http\Response
 */
public function call($method, $uri, $parameters = [], $cookies = [], $files = [], $server = [], $content = null)
{
    $this->currentUri = $this->prepareUrlForRequest($uri);

    $symfonyRequest = SymfonyRequest::create(
        $this->currentUri, $method, $parameters,
        $cookies, $files, $server, $content
    );

    $this->app['request'] = LumenRequest::createFromBase($symfonyRequest);

    return $this->response = TestResponse::fromBaseResponse(
        $this->app->prepareResponse($this->app->handle($this->app['request']))
    );
}

從 function parameter 和 return，大概就知道使用這個方法沒辦法塞 header 值。

但是若透過 SymfonyRequest 的話，則可以設定 header 內容：

$request = SymfonyRequest::create();
$request->headers->set('acccess_token', 'ooxx');

因此，若需要自訂 header，則必須 override 原本的 call() 方法。以下是自己改寫的 trait：

use Illuminate\Testing\TestResponse;
use Symfony\Component\HttpFoundation\Request as SymfonyRequest;

trait ApiTokenRequestTrait
{
    public function call($method, $uri, $parameters = [], $cookies = [], $files = [], $server = [], $content = null, $headers = [])
    {
        $symfonyRequest = SymfonyRequest::create(
            $uri,
            $method,
            $parameters,
            $cookies,
            $files,
            $server,
            $content
        );

        foreach ($headers as $key => $value) {
            $symfonyRequest->headers->set($key, $value);
        }

        $this->app['request'] = \Laravel\Lumen\Http\Request::createFromBase($symfonyRequest);

        return TestResponse::fromBaseResponse(
            $this->app->prepareResponse($this->app->handle($this->app['request']))
        );
    }
}
